Hello Jellby
Thanks for your answer
This option can transform this plugin in a real professional tool
May I suggest to have a file for parameters to store the different options, with 1 option per line, because we can quickly have 5 or more options to add
This file could be for instance stored in C:/Program Files/Calibre2/prince/prince-10r7-win64/bin/
I'm very excited to see the result !
